In the desktop view, we use the primary nav and slide-out menu as overflow for pages. In mobile, I want to show a menu that combines the primary and parts of the slide-out menu. I’ve made a separate menu in WordPress that covers this but not sure how to make it show on the mobile menu. All threads that I’ve seen say to use the slide-out menu for mobile but we are using that on the desktop view. Please let me know if you need more information.
the simplest solution would be set the Full mobile menu to the off canvas and then add your overflow menu items as a Navigation Widget in the Off Canvas Panel.
Then its a case of some CSS to remove one for desktop and the other for mobile.
